Solve biquadratic equation means to find all the values x_{i} , in which will be the equality
a x_{i} ^{4} + b x_{i} ^{2} + c = 0.If in your biquadratic equation there are subtraction signs, before corresponding coefficient in the calculator it is necessary to put a sign a minus (""). For example: x ^{4}  4x ^{2}  5 = 0,coefficients 1, 4, 5. If in your biquadratic equation there are less than three summand, near to an absent coefficient in the calculator it is necessary to put a zero ("0"). For example: x ^{4}  4x ^{2} = 0,coefficients 1, 4, 0. You can input only integer numbers or fractions in this online calculator. More indepth information read at these rules.
